lM PROVEMENT IN PLOWS.

Specification forming part of Letters Patent No.- 212,209, datedFebruary 11, 1879 application filed November 18, 1878.

To all whom it may concern Be it known that I, MARTIN L. GIBBS, ofCanton, in the county of Stark, and in the State of Ohio, have inventedcertain new and useful Improvements in Plows; and do hereby deelare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the lettersof referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a plow, as will be hereinafter more fully set forth. v

In order to enable others skilled in the art to which myinventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the .annexed drawings, inwhich- Figure 1 is a perspective view of my plow. Fig. 2 is aperspective view, in detail, of the jointer and jointer-sheath. Fig. 3represents a greenswardcutter.

A represents the plow-beam, with plow B piy'oted thereto in any of theknown and usual ways. 0 C are the handles, which are rigidly secured tothe land-side and 1nold-board of the plow, said handles being connectedby rounds a. The land-side handle has a slotted plate or casting, D,rigidly secured to it on the inner side. This plate or casting extendsabove one of the rounds, and is turned downward at its inner end,forming an arm, through which the said round passes. The body of theplate D is slotted, as shown at 00, and the rear end of the beam A restson said plate and is fastened thereto by a bolt, 1), passing through theslot in the plate and through the end of the beam. By these means thebeam can easily and quickly be adjusted at any angle with relation tothe plow for taking more or less land, as desired.

Gr represents the jointer, and F the jointersheath, the latter beingheld to the plow-beam A by means of a clip, E. The jointer-sheath. F isbent at or near the center on a curve, but so as to form a horizontaland a vertical part, which prevents choking in the use of the same. Thejointer G is formed at the rear with a plate or bar, (I, having alongitudinal slot, y, and the end of the jointer-sheath forms a foot, f,which is fastened to said bar by a bolt, 6, so as to allow the jointerto be moved sidewise when the beam of the plow is moved from a two to athree horse plowing, or in or out of land.

Instead of a bolt to connect the jointer to the sheath, I may use aclamp similar to the clamp or clip E, when, of course, there will be nonecessity for the slot in the rear bar of the jointer.

In connection with the plow, I also use a stationary cutter, I, for thepurpose of cutting the greensward, which cutter differs from the oldstyle of cutters in inclining or leaning forward instead of backward.The old eutterincreases the draft, whereas mine diminishes it. Thiscutter may be made with one or two outting-edges, both forms beingrepresented in Fig. 3. The cutter is attached to a sheath, J, which maybe fastened in any suitable manner either to the post or beam of theplow.

- Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The combination of the sheath I bent to form the foot f, the jointer Gr,provided with the slotted bar (I, and the bolt 6, all substantially asand for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this9th day of November, 1878.

MARTIN L. QIBBS.
